【摘要】 本文阐述了在大倾角“三软”煤层条件下，选择了走向长壁采煤方法和合理的支护设计；坚持了初撑力第一的观点；实施了单体液压支柱“阻力监控”方法；保证了支护系统具有良好增阻性能和初撑刚度；成功地解决了倾角２５～７５°，煤层松软，顶板破碎，支柱扎底、复杂困难条件下安全开采；实现了稳产，高产，高效，安全生产，为大倾角安全开采探索了一条新路。更多还原

【Abstract】 he author of the paper has summarized thesuccessful experience of safely safely mining soft coal seamsinclining in the range of 35～75°with fragmenting roofand soft floor that can’t bear the prop, and of realizingsteady, safe,highly yielding and efficient production. Heattributes these to the use of longwall mining on the strike,rational design of supports,holding the viewpoint of settingload first,and using resistance monitoring method forsingle hydraulic props to ensure the resistance of thesupporting systerm.更多还原
